CO2 Sequestration

CO2 sequestration involves knowledge of modeling technologies to identify issues with the existing injection strategies and provide recommendations for improved reservoir management. Petrotel has unique expertise in developing a comprehensive geologic model of the reservoir with accurate quantification of natural heterogenity including evaluation of caprock integrity, CO2 source and sink assessment with a detailed reactive transport model,CO2 EOR modeling and making recommendations for improved recovery and FDP.

Petrotel has the experience in developing comprehensive numerical models for evaluating all sequestration mechanisms

Hydrodynamic (mobile) trapping

Residual gas trapping

Aqueous trapping

Mineral trapping

Oil trapping

We objectively evaluate fate of CO2 injection when

Hydrodynamic (mobile) trapping only

Hydrodynamic trapping with hysteresis

Solubility in brine included with hydrodynamic flow with hysteresis

We also develop and analyze effects of heterogeneities in natural reservoirs for CO2 storage based on outcrop analog studies.
